So this pen was bent and I thought about how to straighten this. I figured heat made it warp so maybe heat will make it go back to original shape. I was smart enough to know not to hold a match under the pen to heat it, so I carefully held it over the steaming spout of a tea kettle. The not so black faded hard rubber immediately turned white and melted like a wet noodle.
So I said to myself...this is not the way to fix a pen when you have no idea what you are doing!. So I explored, read books, searched online and learned all about pens from others that were so kind to share their knowledge.
Moral of story...search, read, visit every site about pens and be sure to come back here to share your passion.
